Scroll area not scrollable

[Daddedebad]

Hey, I have an issue getting my scroll area UI started using QT 5.12.2 in visual studio...

I have a scroll area with 2 images in it, as can be seen in the image below the scroll bar is there but inactive:

This is how I open my UI with the scroll area:

scrollUI* w = new scrollUI(this);
w->setWindowFlags(Qt::Window | Qt::CustomizeWindowHint | Qt::WindowTitleHint);
w->show();

and here is the code found in the .ui file:

#endif // UI_SCROLLUI_H

The .h file for the scrollbar is following:

#pragma once
#include "ui_scrollUI.h"

class scrollUI : public QWidget
{
    Q_OBJECT

public:
    scrollUI(QWidget* parent = nullptr);

private:
    Ui::scrollUIUI ui;
};

The .cpp file:

#include "scrollUI.h"

scrollUI::scrollUI(QWidget* parent) { ui.setupUi(this); }

apologies for the poor names, tried to rename my variables... and sorry if it is a common question.
